Thanks for following up. Dave certainly deserves the title of master in my view, though he is certainly not the only one. His contributions to the worldwide practice of bouldering are matched only by Frederic Nicole, making his a particularly valuable presence in the book. To have both Fred and Dave in the volume was an extraordinary opportunity.

In my view, Gill, with his innovations in terms of ideas and technique, transformed bouldering from its more casual origins to a significant independent discipline. His legacy is one every serious boulderer respects to some degree.
